American geography may be said to have had three important problems to solve, in modern times. The first and second of these, related to the source of the Missouri, and to the course and termination of the Columbia. Both, were substantially resolved by the expedition of Lewis and Clark, under the administration of Mr. Jefferson. It is to be borne in mind, however, that but one of the three forks, up to which the Missouri was traced, has been explored, that its two northwestern branches have not been ascended, and that, consequently, we do not actually know, which of its primary tributaries is the longest, or brings down the greatest volume of water.

The true source of the Mississippi, which forms the third topic of inquiry, was brought into discussion at the same period. And immediately after the acquisition of Louisiana, the American government sent an officer, with a suitable body of men, to determine it. Lieut. Pike, who was selected for this service (who, nine years afterwards lost his life as a general in the service, at the taking of York) did not, however, set out early enough in the season (1805) to accomplish the object. After the selection and purchase of the site, on which the fort near the Falls of St. Anthony, is now situated, he encountered delays in ascending the rapids characteristic of that part of the Mississippi. Winter overtook him before reaching the junction of the De Corbeau. He prepared for its severities by erecting a block house, for the security of his provisions and men. He then proceeded with a small detachment, on snow shoes to Sandy Lake, and Leech Lake; two points of central influence, which were then occupied by the North West Fur Company. As the partners of this company consisted of foreigners, and their operations were continued after the legal transfer of the country to the American government, Lieut. Pike would have been justified in making a seizure of the valuable furs then in their possession. He did not, however, adopt this course, and exhibited a magnanimity in relation to it, which is in accordance with his subsequent acts of disinterested intrepidity. He collected the geographical data, which are embodied in his published map and journal, and returned from his wintry station, on the opening of navigation in the spring.

No further effort was made to explore the sources of the Mississippi, for several years. In 1820, Gov. Cass, then administering the government of Michigan Territory and exercising jurisdiction over Indian affairs, obtained the sanction of the general government to visit the region. He left Detroit, with a party of thirty-eight men, including the gentlemen composing his suit, during the latter part of May. He was supplied for a journey of four months. After traversing the coasts of Lake Huron, and visiting Michilimackinac, he proceeded north-westward, by ascending the primitive summit at the Falls of St. Mary, went through the extended and picturesque basin of Lake Superior, and first struck the waters of the Upper Mississippi at Sandy Lake. To this point he was accompanied by the military escort, and by the train of larger canoes employed to transport stores and baggage. But the fatigues which the men had undergone in crossing portages, added to the low state of the water, induced him to form a permanent encampment at this place. And he proceeded with a select party, in canoes to explore the Mississippi.

It was the middle of July when the expedition reached Sandy Lake, and the difficulty of subsisting so large a party in so remote a position, with the constant claims of suffering and hungry tribes, who presented themselves at every point, began to be severely felt. The exploring party, which was now organized, went out, under a sense of these circumstances, and with a feeling of the responsibility pressing upon the claims of the expedition in other quarters, which limited the time applicable to the ascent. They entered the Mississippi on the 17th of the month, and found a strong current, with alluvial banks, and a vegetation indicative of a fertile soil. For the distance of about one hundred and fifty miles, above this point, the party found no diminution in the average strength of the current, which was frequently accelerated by rapids. The latter then assumed a more formidable aspect for ten or a dozen miles, at the end of which they were terminated by the falls of Peckágama. At this cataract, the river, which below has its course through alluvial banks, densely wooded, is compressed between rocks of granulated quartz, over which it rushes with a velocity, which would seem to threaten destruction to any species of craft that should attempt the descent. It became necessary, at this point, to transport the canoes and baggage from two to three hundred yards over land.

On reaching the Peckágama summit, the channel of the Mississippi was found to flow more directly from the west, with a comparatively sluggish current. But the most distinctive trait of this part of the river was found to consist of a series of extensive savannahs, through which the river displays itself in the most elaborate windings. The junction of the Leech Lake branch takes place at this plateau, at the computed distance of fifty-five miles above the falls. After passing this point, the course of the river is again, generally, from the north-west, about forty-five miles to Lake Winnipec, a handsome body of clear water, estimated to be ten miles broad. The course of the ascent is then west, for about fifty miles, at which distance the river is found expanded into a more considerable lake, presenting an area of limpid water of, perhaps, 120 square miles. This sheet, which has subsequently been found to be the largest expansion of the Mississippi, is since denominated Cass Lake. It was the highest point reached. The party entered it on the 21st of July. The question of pursuing the stream further, was then submitted by Gov. Cass, to the gentlemen composing his party. Anxious as all were to see the actual source of so celebrated a stream, their wishes were controlled by circumstances. Inconveniences had been felt from leaving the supplies at so considerable a distance below, and as the waters were found to be low, and the preparations inadequate for a journey of indefinite extent, a decisive opinion was expressed in favor of a return from this point. This decision was immediately carried into effect.

From the best information that could be obtained, the Mississippi was represented to have its origin in a lake called La Biche, supposed to be sixty miles distant, in a north-west direction. Upon this estimate, the length of the river was computed to be 3038 miles, and by a series of approximate estimates, its altitude placed at 1330 feet above the Atlantic. Numerous rapids and lakes were, however, stated to exist in this remote part of the stream, and a degree of vagueness and uncertainty exhibited in relation to it, which evinced, that the traders, who were relied on for information, either, had seldom frequented it, or preserved an indefinite recollection of its geographical features.

Such was the state of public information on this point in 1820. A veil of obscurity was still cast about the actual source of the Mississippi, which there was no further attempt to remove for ten or eleven years. In 1830, the writer of these sheets was directed to proceed into the Chippewa country, north-west of Lake Superior, in the execution of duties connected with Indian affairs. But the instructions were received so late in the season, that their execution became impracticable until the next year. In the mean time, means for more extensive observation were provided, a physician and botanist engaged, and a small detachment of troops, under the command of a subaltern, ordered to form a part of the expedition.

This expedition numbering twenty-seven persons, exclusive of guides and Indian auxiliaries, employed on the portages, left St. Mary’s at the foot of Lake Superior, late in June 1831. After entering, and coursing around the shores of Lake Superior to Lapointe, it was found, from every representation, that the low state of the water on the Upper Mississippi, would render it difficult, if not impracticable, to reach the bands at its sources, during the drought of summer. Public reasons were, at the same time, urgent for visiting the interior bands, located between the group of islands at the head of Lake Superior, and the Mississippi—where a useless and harassing conflict was kept up between the Sioux and Chippewa nations.

The expedition returned eight miles on its track, and entered the mouth of Mushkigo, or Mauvais river of Lake Superior. This stream, which carries down the waters of an extensive slope of highlands, is embarrassed with permanent rafts of flood wood, and with numerous rapids, presenting an arduous ascent. The axe, the canoe-pole, and the carrying-strap, were alternately employed in the ascent, and they were employed under the influence of the midsummer’s heat, and the annoyance of the hordes of smaller insects, who are on the wing, in this secluded valley, during the greater part of the twenty-four hours. This stream was ascended one hundred and four miles, to the portage. The goods and canoes were then carried 8¾ miles, across highlands, to a lake called Kaginógumoc, or the Longwater; and thence by four separate portages, and three intervening lakes, to the Namakágon river. The latter was descended one hundred and sixty-one miles, to its junction with the St. Croix, of which it is the right fork, and the channel of the latter pursued to Yellow River. From this point, where a public council was convened, the expedition re-ascended the Namakágon to the portage into lac Courtorielle, or Ottawa Lake. This portage consists of a carrying place of three miles and a lake, then another carrying place of 750 yards and a lake, from the latter of which there is a navigable outlet into the Ottawa for canoes.

Ottawa Lake is a sheet of water about twelve miles long, having an outlet into the Chippewa river of the Upper Mississippi. In order, however, to visit certain hostile bands, a portage was made from this outlet (after following it down about half a day’s journey,) of 3½ miles, into lac Chetac, the principal source of Red Cedar river. The latter was then pursued, through four principal expansions, called Wigwas, Warpool, Red Cedar and Rice Lakes, to its falls. A short portage over horizontal sand-rock, interrupts the navigation, after which there is a series of rapids, extending about 24 miles. Deep and strong water was then found to its junction with the Chippewa river, which it enters at the estimated distance of 40 miles from the confluence of the latter with the Mississippi, (on its eastern bank.)

The entire line of country travelled by this interior route was 643 miles. The Mushkigo, the St. Croix, and the Chippewa, were the rivers, which by their common origin and interlocking on the summit lands, afforded this communication. Many bands of Indians were visited in their fastnesses, where they had hitherto supposed themselves out of the reach of observation. Councils were held at various points, and presents distributed. And the pauses afforded by these assemblages, and by the necessary delays of overland transportation, furnished opportunities for preserving notes on the manner of living, among those bands, and their population, traditions and resources, as well as the geographical features and the natural history of the country. On entering the Mississippi, the truth of the information, derived on Lake Superior, respecting its depressed state, was verified. Extensive portions of its outer channel and bars, were found exposed and dry. The party encamped on a sand bar formed by the junction of the Chippewa, which is usually several feet under water.

From the mouth of the Chippewa, the expedition descended the Mississippi to Galena, in Illinois. While at Prairie du Chien, the murder of twenty-six Monomonee men, women, and children, by a war party of the Sacs and Foxes, which had transpired a few days previous, was the subject of exciting interest. It was narrated with all its atrocious circumstances. A flag waved over the common grave of the slain, and several of the wounded Monomonees, who had escaped the massacre, were examined and conversed with. This affray unparalleled for its boldness and turpitude, having occurred in the village of Prairie du Chien, in the hearing of its inhabitants, and in sight of the fort, was made the subject of demand by the government for the surrendry of the murderers, and produced the concentration of troops on that frontier, which eventuated in the Indian war of 1832. Some excitement was also felt at Galena, and its vicinity, in consequence of the menacing attitude which the Sacs and Foxes had recently assumed, in the vicinity of Rock Island, and a general mistrust felt of their sincerity in the treaty concluded with the United States a short time previous.

At Galena, the exploring party separated, part returning in canoes up the Wisconsin, and part crossing the mine country, over the branches of the Pekatolika, and by the way of the Blue Mounds, to fort Winnebago. From this point, Fox River was descended to Green Bay, and the route of the lake coast pursued northward to the straits, and to the Sault of St. Mary.

A narrative of this expedition, embracing its principal incidents, and observations on the productions of the country, is in preparation for publication by one of the gentlemen of the party. In the mean time, the official report transmitted to Government, and submitted to Congress by the War Department, together with remarks in a series of letters on the mine country, are subjoined in the appendix to this volume.
